Hernán Núñez de Toledo y Guzmán (Valladolid, 1475 - Salamanca, 1553) was a Spanish humanist, classicist, philologist, and paremiographer.
At the age of 50, he retired from teaching to dedicate himself fully to research, although he seems to have still given classes on Hebrew at the University of Salamanca.
It inspired imitators in Spain and abroad, such as the French work Proverbiorum Vulgarium Libri Tres (1531) and the Italian Opera quale contiene le Dieci Tavole de proverbi (Turin, 1535).
In 1519, he published a Greek and Latin text of the letter “To the Christian youths,” written by Saint Basil.
He published critical studies on the works of Pliny the Elder, Theocritus, Seneca, and Pomponius Mela.
